wondering if you can use an 8speed crank running all 9 speed components?

yes

The cranks dont care how many gears are out back, neither does the front derailleur.

if your 8spd crank was made after 9spd came out, they should be "8/9 compatible"; older than that may cause some finicky front shifts and extra noise. but go for it, as those problems are usually pretty small.
